I reached out to Pentius a couple of weeks ago about spec sheets for their filters or ISO efficiency test results for their filters. I finally heard back today from Don Betz at Pentius in a reply that was a cookie cutter "We thank and love you and check out all of our great products." But no mention anywhere of anything close to answering my original question.
So I am feeling less enthusiastic about that case of filters that I just bought. (removed - MOD)
